I have to answer three questions about limits of Riemann sums, and I can't remember how to figure it out. I know it involves sequences with sigma but I don't know where to start now.
the first one I have is written with the integral from 2 to 5 (x^2 - 1)dx
can someone please get me started or show the steps so I can do the rest of my homework?
The question reads:
Find a formula for right hand endpoint sum by dividing the interval into n equal subintervals. Then take the limit of these sums as n approaches infinity to calculate area under the curve [a,b]. f(x)=5x^2 over [1,2]
